sh: add Video Output Unit and AK8813 video encoder support on ecovec
Ecovec uses the AK8813 video envoder similarly to the ms7724se platform with the only difference, that on ecovec GPIOs are used for resetting and powering up and down the chip. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
